Wandering through Target with my daughter, she stopped me for the new Lego line “Friends.” It’s a pack of cute, Lego-sized dolls where you built them and their play sets. Brilliantly simple idea and a fine execution.

She asked me to read the descriptions of the four girls on display. What took me by surprise was that they actually had negative sides of their personalities. One of them loves to plan parties, but she can be bossy. One of them loves to perform, but is a bit of a drama queen.

This, I thought, was fantastic. Most of the times, personalities for kids’ toys are very straight and narrow. They never have a bad side to them. “This one loves animals and the color pink!” That’s about as much as you’ll get from some of them.

It’s so bad that the “books” that are put out to support the toys (or do the toys support the books?) just pick a toy as the main character and put words in her mouth. The characters are that interchangeable that it just doesn’t matter who says or does anything.

So I was pleasantly surprised that, in just a few short sentences, the Lego Friends were well described and set up enough things for them to do.What I Learned: For a story to happen, there has to be conflict. The best conflict comes from between characters. But they have to be different enough for that to happen.
